Problem: Recently I have noticed that shifting gears is becoming increasingly difficult, especially from N to 1st gear and from 3rd to 4th. It doesn't happen all the time but like I said, it's increasing.
The problem is that I am hearing the synchronizers grind when I try to shift gears. Sometimes when I try to shift to 1st it simply will not go and I can feel the tranny shift beneath my feet. Also, for the past week there has been a low volume high pitched squeal coming from the Jeep. When I push the clutch in a little bit it would stop.

Attempt One (to be done tomorrow 3/29/04): Going on advice from my Brother in Law I'm gonna try and check the tranny fluid by pulling the plug and using a sophisticated piece of equipment called my finger. If it's low I'm gonna fill it up and try that.

Sounds like the sync's are going out in it. Not a real hard job to do. Just time consuming - considering everything that has to be disassembled/re-assembled.
You might try going to a synthetic fluid in the trans and see if that helps.

hahaha not real hard haha

edit: i guess i could be helpful here i had a similar problem last summer turns out the 2nd or 4th (i forget) gear syncro would get itself stuck on the shaft instead of spin freely (something like that) and it just screwed up all the workings, but it was because one of the bearings (an expensive one like $140 form the stealership) was worn and had play, so i would say if you do feel comfortable takeing the thign apart and have a good schematic of the transmission, i'd say replace your syncros that look worn and any bearings you can HTH_________________94 Jeep YJ 3.5 inch lift 33's Tera SYE and CV driveshaft, More Sport Cage, BL/MML, rust

Update: When I pulled the fill plug and stuck in my finger I couldn't feel the "pool" of tranny fluid. While underneath I noticed that my tranny housing was well....grimey. Like I had sprayed oil on it and drove downa dirt road kind of grimey. I'm guessing that my seals are leaking.

I'm going to try some 90W tranny fluid and some Stop leak. I figure synthetic would be great, but it is thinner, so it would leak out faster than something thicker._________________But hey, WTF do I know? I kick Hippies for fun.

I put some 90w Gear Oil in and some Lucas Tranny Stabilizer Fluid (Stop Leak). Between the two of them it help a quart. Guess I was low huh? I think that the rear seal busted on my tranny, or it's at least leaking.

I'd love to switch to redline, but I can't find it around here and it's synthtic, so it would leak out faster. I'm gonna try and stop the leak first, then try some new gear oil.

Thanks for all the replies, and any more would be greatly appreciated._________________But hey, WTF do I know? I kick Hippies for fun.

Figured I would move the conversation about your tranny back here....seems apropriate.

So, I understand that it's leaking, but did adding gear oil smooth out the shifting? Or are ya gonna need a rebuild?

Lookin at a rebuild I guess. I started getting this awful squealing sound when I was descending a hill in 1st gear (4Lo) and it went on all day. Now whenever I have the jeep in gear and the throttle isn't applied it is freaking wailing. _________________But hey, WTF do I know? I kick Hippies for fun.
